    // 1、多行字符串
    let str1 = `In JavaScript this is 
    not legal.`
    console.log(str1);

    // 2、字符串插入变量和表达式。变量名写在 ${} 中，${} 中可以放入 JavaScript 表达式。
    let name = "Mike"
    let age = 27
    let info = `My Name is ${name},I am ${age + 1} years old next year.`
    console.log(info)// My Name is Mike,I am 28 years old next year.

    // 3、字符串中调用函数
    function f() {
      return "have fun!"
    }
    let str2 = `Game start, ${f()}`
    console.log(str2)
